STREET BARRIER.

Application filed November 22, 1926. Serial No. 150,013.

This invention relates to an improved device such as is frequentlyreferred to in the trade, as a street or road barrier, the same havingmore particular reference to a structure of this kind which is used inroad and street construction work, to prevent passage of pedestrians,and vehicles over incomplete surfaces.

Briefly, the invention has reference to a longitudinally extensible railhaving heads on its outer ends upon which supporting legs are pivotallymounted in a manner to permit them to be swung into parallelism with therail to provide an exceptionally compact arrangement such as may be convcniently handled in transportation and disposition for use.

More specifically, the invention has reference to a rail which iscomposed of a central tube having a pair of cylindrical end sectionstelescoping into the same, whereby to permit the rail to be adjusted toaccommodate the particular area to be protected.

In addition, there are flanged blocks on the ends of the rod sectionsand the supporting legs, which are disposed in downwardly divergingrelation, are pivotally connected to said blocks and engageable with theflanges when in supporting position.

Other features and advantages of the invention will become apparent fromthe following description and drawings.

In the drawings Figure 1 is a perspective View of the complete deviceshowing the same set up for use.

Fig. 2 is a view with parts in section and in elevation showing thestructure folded into a condition for convenient handling.

Fig. 3 is a section taken approximately upon the plane of the line 3-3of Fig. 2.

The rail is generally designated by the reference character 1 andincludes a central open ended tube 2 and a pair of extensible rodsections 3 of cylindrical cross section. These are slidably mounted inthe tube, and are provided at their inner ends with outstanding heads 4and engageable with inturned flanges on the outer ends of the tubesection 2 to limit the outward sliding movement. The rod sectionspreferably engage the interior of the tube with suiiicient friction topermit them to be adjusted to and held in convenient position, to guardagainst accidental and undesirable collapsing.

The blocks which are of general triangular configuration, arerepresented by the reference characters Sand are provided within theirinner faces with sockets,'into which the rod sections 3 are fitted. Eachblock is provided with outstanding stop flanges 6 which terminate shortof the apex portion of the block. Then pivotally connected as at 7 tothe apex portion are the supporting legs 8, which are simply in the formof metal strips.

Assuming that the structure is in the position shown in Fig. 1, it willbe seen that the supporting legs 8 will rest against the flanges 6 sothat they will be prevented from swinging outwardly. The weight of thestructure itself will serve to maintain the legs against accidentalinward swinging. The rod section 3 may be adjusted to the desired extentto render the device sufficiently long to provide a proper guard for thearea of the road surface to be protected.

When the device is ready to be removed and transported to some otherpoint, the legs can be swung up into the folded state represented inFig. 2, and the rod sections 3 pushed into the tube 2. This renders thestructure decidedly compact. I

It is believed that by considering the description in connection withthe drawings, a clear understanding of the construction of the method ofuse and operation of the invention will be understood. Therefore a morelengthy description is thought unnecessary.

While I have described the preferred embodiment of the invention, andhave especially stated that it is used as a street or road barricade orbarrier, it is to be understood that the device may equally well serveother purposes within the meaning of the appended claims.

Having thus described my invention, what I claim as new is 1. In abarrier structure of the class described, a rail comprising a centraltube, a pair of cylindrical end sections slidable in said tube,cooperating means between the end sections and tubes for limiting theoutward sliding movement of the end sections, heads on the outer ends ofsaid endsections, and supporting legs pivotallyconnected to said heads,said heads being of a design to dispose said supporting legs indownwardly and supporting legs pivotally connected with said heads andassociated with said flanges in a manner to permit them to be disposedindownwardly diverging relation 10 or to aliowithem to be swmmg up intopar- V a-llelism with said rail.

In testimon; whereof I affix my signature.
